From the factory subframes are installed quickly so as not to slow down the production line. This is done with ill fitting bolts that leaves an inconsistent mating surface between vital components. Mazda RX-7 [FD3S] Subframe Collars install between the subframe and the chassis and take up the slack left by these undersized bolts. The result is improved handling, more consistent camber settings, less vibration and improved braking.
- Front & Rear Set
- Easy Install Requires Lowering of Subframe (NOT Removal)
- Solid Aluminum Construction

Subframe Collars
Nice product at a decent price point. I was able to install with the vehicle on jackstands and without fully removing the subframe. Lining up the collars was a little difficult doing it this way, but take your time and you'll get it. Hard to tell the difference it made on the road since I upgraded all of my suspension at the same time.

James D. United Statesthey even work with Ronin subframe
i decided to order these while i was replacing the subframe for my swap. they crushed up very well and filled the oblong hole in the Ronin subframe nicely. should solidify the front end well. I will install the rears in once I have to replace my differential
